The European Union has set an ambitious goal to reduce emissions by at least 55% by 2030 compared to 1990 levels and to achieve a climate-neutral continent by 2050. This goal seems too ambitious and it is unlikely that it will be realistically fulfilled. At the level of the European Union, several legally binding acts are being adopted in the area of air, water or soil and agriculture, with the aim of setting harmonized rules in all member states. At the same time, there is a revision of several existing legal acts. However, such a procedure represents only one part of the goal. The second, more important one, lies in the willingness of states to properly transpose and apply European rules at the national levels. In the last 8 years, the European Commission has started more than 2,800 infringements in relation to member states due to incomplete or incorrect transposition or bad application practices related to the limits and rules set by European directives in the environment. Member States have a problem to fulfill their obligations and I think that this problem will continue in the future, despite all the efforts of the European Union to achieve the goals set through the European Green Deal. With the work presented, I want to point out the shortcomings and complications which arise in connection with the fulfillment of goals at the level of the European Union in the area of the environment.
